Tungsten contact breaker points, once prolific in automotive ignition systems, have become virtually unobtainable in recent years. Tungsten is a robust, brittle metal with a high resistance to temperature and a high melting point - withstanding surface pitting for 100's of engine hours.
By a happy chance, we have obtained a decent stock of solid tungsten discs measuring Ø0.160" x 0.045" thick with ground and polished faces. These can be easily brazed to spring steel or headless bolts with a silver based material such as Easyflo. In theory at least... the tungsten can be machined with a carbide tool run at 100 - 200 rpm with a good supply of coolant.
Please note: These are sold EACH. If you need a pair, please order 2 - or perhaps more to account for losses?
